# 48.40. `pg_seclabel`

The catalog `pg_seclabel` stores security labels on database objects. Security labels can be manipulated with the SECURITY LABEL command. For an easier way to view security labels, see Section 48.66.

See also `pg_shseclabel`, which performs a similar function for security labels of database objects that are shared across a database cluster.
